In 'Whose Shadow Is That?', players assume the role of a quirky paranormal investigator named Luna Shade who specializes in uncovering the truth behind mysterious shadows appearing in a small, poorly-lit town. As whispers of ghostly apparitions and shadowy figures spread, Luna must interrogate eccentric locals, delve into historic archives, and use a unique shadow manipulation mechanic to uncover hidden truths. Players will navigate through vibrant, risk-laden environments where choices dictate outcomes and lead to multiple endings. With puzzles based on light and shadow, the objective is to unravel who—or what—is casting a dark silhouette across the lives of the townsfolk.
